TYPE-MOLD.

Specification of Letters Patent.

Patented June 23, 1908.

To all whom it may concern:

Be it known that we, CHRISTIAN HUFF, EDWIN BOND WHITE, and JAMEs THOMASCARTER, citizens of the United States, residing at Baltimore and Stateof Maryland, have invented certain new and useful Improvements inType-Molds and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use same,reference being had to the accompanying drawings and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in type molds, andthe object of the invention is to produce a simple and eflicient meanswhereby a mold may be adjusted to cast any size of type, and in theprovision of adjustable gate plates for the purpose of bringing the gateto the center of the mold, whereby there may be an equal distribution ofmetal to all parts of the mold, thus insuringa perfect type of properweight and having perfect faces.

Our invention consists further in various details of construction andcombinations and arrangements of parts which will be hereinafter fullydescribed and then specifically de-.

fined in the appended claims.

We illustrate our invention in the accompanying drawings, in whichFigure 1 is a side elevation of our improved adjustable mold for makingtype, a

portion of the view being shown in vertical section. Fig. 2 is a topplan view of the apparatus. Fig. 3 is a side elevation of the mold, aportion being shown in section. Fig. 4 is a detail perspective view ofthe adjustable gate plates, the recessed block or plate holding thesame, and the nozzle through which the molten metal is intro ducedthrough the gate. Fig. 5 is a detail perspective view of the adjustableto and side of the mold, and Fig. 6 is a sectiona view of a slightmodification of the invention in which, instead of having the gateplates adjustable, they are adapted to be held sta tionary and thebottom and top of the mold are made adjustable.

Reference now being had to the details of the drawings by letter, Adesignates the frame of the apparatus which is preferably of metal andprovided with a lateral extension A upon which a movable carriage orblock B is mounted, said carriage having an integral lug B projectingfrom the bottom thereof which is adapted to have a play in an elongatedslot A formed in said extension. Pivotally connected to the lug B is alever C which is adapted to be oscillated in any suitable manner, as bymeans of an eccentric D mounted upon a pin D.

A spring E is shown in Fig. 1 of the drawings as being connected tothelever C, where by the lever, after having been driven forward by theeccentric, may be returned to its normal position. The mold proper con1prises an adjustable top F, an enlarged detail view of which is shownin- Fig. 5 of the drawings, and said top has a downwardly projectingportion forming the side wall F of the mold, and has a laterallyprojecting flange G under which a matrix H is adapted to be held againstthe edges designated by letters K and K in Fig. 5 of the drawings, thusforming the face wall of the mold. Rising from the block F is a stem Iwhich is adapted to be raised and lowered by any suitable mechanism, notshown.

J designates a longitudinally movable bar, it being our purpose toprovide as many of said bars as there are thicknesses of type to becast, and the inner end of said bar is adapted to form one wall of themold, said wall being the one o posite the side wall F. Said bar J isadapted to have a longitudinal movement and rests upon the casting Oforming the bottom of the mold and also upon the block or carriage B. Alongitudinal slot J, shown clearly in Fig. 2 of the drawings, is formedin each bar J, and an adjusting nut J passes through said slot and isheld in a threaded opening in the carriage or block B. An uprightportion A at the end of the extension A of the frame carries amicrometer screw R mounted in a threaded opening in said uprightportion, and is adaptec to bear against the end of the bar J for thepurpose of moving the same longitudinally to its proper adjustment forthe width of type to be cast. After the bar J has been adjusted to itsproper position, the carriage B is moved to the position shown in Fig. 1of the drawings, in which the outer end thereof will contact with abuffer a projecting from the upright portion A after which the screw Bmay be tightened to hold the bar and carriage fixed together, afterwhich the mi- '5 may be adjusted.

crometer screw R may be turned back so that it will not interfere in anyway with the end of said bar and also save the screw from unnecessarywear.

The block H is fastened to the plunger H and the matrix holder H isloosely mounted upon said block H and is adapted to be moved at aredetermined moment by mechanism, not il ustrated, whereby the matrixmay be withdrawn from the cast type and allow the latter to be ejectedby the reciprocating movement which is imparted to the bar J by thelever C. It will be understood that the member F comprising the top andside of the mold will also be raised from the t e at a predeterminedmoment by any suitab e mechanism after the type has been cast.

Referring to Fig. 4 of the drawings will be observed a block Q having arecess Q formed in one face thereof for the reception of the two gateplates S and S, each of which gate plates has a recess formed thereinwhereby the two plates may be held in adjusted positions with relationto each other, as shown in said Fig. 4. An adjusting screw S is carriedby the laterally projecting portion of the plate S and is adapted toengage a threaded o ening in the upper end of the plate S, w llereby thewidth of the opening of the gate The ends of the gate plates adjacent tothe margin of the gate are downwardly inclined, as indicated by lettersS and a conical-shaped opening T is formed in the block Q, which openingleads into the recess Q and through which the molten metal from thenozzle T may be introduced to the gate. Said gate lates S and S form therear wall of the mole and the size of the gate may be adjusted to anydesired width by means of the screw 8*, and said gate lates are designedto be adjusted vertical y together for the purpose of bringing the gateto the center of the mold of whatever sized type is to be cast, and saidadjustment of the plates may be accomplished by any suitable means, suchas by the provision of an eccentric W, shown clearly in Figs. 1 and 3 ofthe drawings, which eccentric is-mounted upon a fixed pin WV carried bythe arms V said eccentric being mounted in a recess S formed in one edgeof the gate plate S. Fixed to said eccentric is a lever W the upper endof which is fixed to the pin W, and may be fastened by means of a buttonW in any one of the holes W, whereby the throw of the lever may beadjusted and impart the proper longitudinal movement to the gate plates.

In Fig. 6 of the drawings, we have shown a slight modification of ourinvention in which, instead of providing a stationary bottom for themold, we provide an adjustable one designated by letter V which israised and lowered by any suitable mechanism, not shown, and also themember F forming the top and side of the mold, which is also adjustable,but the gate lates designated, respectively, by letters and U are heldstationary and the removable bars J each is provided with an upwardlyprojecting lug J 6 against which an adjustingscrew J carried by theframe'is adapted to bear, whereby said bar may be adjustedlongitudinally. Each of the bars J is adapted to fit over a movable lugJ mounted upon an arm J which is adapted to have a reciprocatingmovement.

The operation of our invention is as follows. A matrix for theparticular type to be cast is adjusted in the dove-tailed slot in theholder H said matrix adapted to form the face end of the mold. Theparticular holder J for the width of the type to be cast is placed uponthe table or bottom 0 and the adjusting screw J passed throughthe'elongated slot in said bar. The micrometer screw R is then turnedagainst the end of the bar and made to move the bar to the properposition regulating the width of the type to be cast, after which themember F is moved down to form the top and side of the mold, and thegate plates raised or lowered so as to bring the gate opposite thecenter of the mold, as shown in Fig. 3 of the drawings, after which bythe adjustment of the screw S the width of the gate may be regulated toallow more or less of the molten metal to pass into the.

mold. It will be noted that by the provision of the inclined walls S ofsaid gate plates, the latter may be raised or lowered to any desiredadjustment and still allow the molten metal to pass readily through thegate into the mold. By having the gate at the center of the mold willinsure an even distribution of the molten metal, thus forming a perfecttype of proper weight and perfect faces.

The type having been cast, the parts of the mold and the matrix willbe'withdrawn from the type, and at a predetermined moment, alongitudinal movement will be imparted to the bar J X and the typeejected, after which the parts of the mold will be thrown back to theirproper positions to receive metal for an additional type.
